2. Desert – an ecosystem found where there is very little rainfall.  Two kinds of deserts:  Hot deserts  Cold deserts  Hot deserts  Temperatures are very warm all year round  The summers are very hot  Cold deserts  Short, warm summers  Long, cold winters  Found in places near the north and south poles

3. Climate The desert is very dry and warm. A very little amount of rain rains a year. Some deserts can be over 100 degrees F. That’s so hot.

4. Location The desert is located 30 degrees latitude. Many deserts form around 30 degrees latitude because this region is the subtropics. The subtropics experience high air pressure, which means clouds will not form, and because there are no clouds, there is no precipitation. Another reason you get deserts is because they are far inland and thus far from a body of water that can provide the humidity for clouds and rain.

5. Some deserts are in the Mountains. The Mojave desert is the name of the desert that is located in California.

6. Desert Plants  Many plants are found in the desert. They usually grow close to the ground.  These plants have special parts that help them save water.  The special parts are: thick stem, shallow and wide roots, and thick skin covered with spines instead of leaves.

7. The cactus, saguaro, creosote bushes, and other plants.

8. Desert Animals  There are many animals in the desert.  They can survive by eating other animals or by eating plants that store water.  To protect them from the hot sun, they stay in the shade or in their shelter.  Animals may build their shelters inside plants.  Some animals sleep during the day and are active at night.  Some animals have hard shells to protect them from losing much water.  More animals live in hot deserts than in cold deserts.
